To all whom t may concern:

Be it known that I, ROBERT MIEHLE, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Mechanism for Adjusting Paper Upon Feed-Boards, of which the following is a full, clear, concise, and exact description.

My invention relates to boards from which paper is to be manually fed to folding machines, printing presses, etc., and has for its object the provision of means for changing the positions of sheets or lifts of paper with reference to such boards. In practising my invention I employ roller mechanism to the rear of such boards to impart or permitmovement of sheets or lifts of paper longitudinally of the boards, this roller mechanism desirably including a plurality of rollers having parallel axes of rotation that are at right angles to the general line of travel in which the paper is being fed. The boards are desirably rearwardly continued into the region of the rollers and when they are thus continued the rollers preferably permanently lproject above such rearward continuations to'havetractive engagement with the paper upon the same. -When the boards have rear paper or liftreceiving divisions there are afforded composite stationary and movable paper supporting structures tothe rear of the feed boards proper.

' I will explain my invention more fully by reference "to the accompanying drawing showing the preferred embodiment thereof and in which Figure'l is a plan View of a feed board 'equipped'with my invention and shown in association withl an impression cylinder of a printing press, ,parts being broken away; Fig. 2 is a View on -line '2 2 of Fig. 1; Fig.Y 3 is a detail view of some of the parts taken on the line 3 3 of Fig. l; and Fig. 4 shows a detail of construction taken on the line fir-4f of Fig. l.

Like parts are indicated by similar characters of reference throughout the different figures.

The drawing shows Vthe association of a feed board equipped with my invention with ay rinting press (of which a printing cylin er 1 'is shown in Figs. 1 land .2) "but the invention is not .to be limited' to such association.

The front division 2 of the feed board is the feeding end thereof from which the sheets of paper are' delivered singly to be operated upon by the mechanism to which they are to be fed such as a printing press. The rear division 21 of the board supports the lift of paper indicated at 8 in Fig. 2, the sheets being led from the lift or pile of paper 3 to the feeding portion 2 of the board which is customarily hinged at 4:. The lift supporting portion of the feed board is mainly the rear division 21, a portion of the lift being usually carried upon the rear portion 0f the feed board division 2. The rear division of the feed board is equipped with rollers 5 having spherical enlargements or sections 6 that project through circular openings in the feed board slightly above its paper supporting surface or the plane of its paper supporting surface to have tractive engagement with the paper that is upon the same. The mountings for the rollers are so disposed as to have the aXis of rotation of the rollers suiiiciently below the paper supporting surface'or the plane of the paper ysupporting surface to permit the rollers to project only slightly above such surface or plane, and the rollers are disposed transversely of the board so that they may rotate longitudinally of the board or in the line of feeding. The rear portion of the forward division 2 of the feed board is equipped with rollers 7 having spherical enlargements or sections 71 that similarly project through circular openings in this feed board division to rhave tractive engagement with the ,paper that is uponthe same. These rollers are preferably limited to movement longitudinally of the'feed board and the paper is 'prevented from working in between the rollers and the feed board owing to the presence of portions of the feed board between the roller sections 6 and the roller sections 71. In the'preferred form of the invention the portions of the feed board bein theregion of thev rollers except for the f mere presence of the disconnected yopenings through which the spherical sections of the rollers project. All lof the rollers 5 upon the reardivision ofthe board are preferably `equipped with roller driving mechanism one of the two rollers upon the forward division of the board7 the rear roller upon the for.-

ward division of the feedboard being desirably an idler. The driving mechanism 'illus--V trated comprises sprocket pinions 10 located upon one side' of the feed board and fixed carry the rollers 5. An endless sprocket chain 12 passes over the tops of theseV pinions and is maintained in engagement with'the teeth of these pinions by means of the guard plate 18. VThe end'of one of the shafts 11 that carries a sprocket piniony 10 is desirably equipped with a hand crank 17 *or Aany other means for furnishing power, the shaft 11 selected for the attachment of the crank A17 thereto being desirably that upon which the rearmost roller 5 is mounted. The neXt to the foremost roller 5 also has. crank 18 or some other suitable means for furnishing power connected therewith, the crank 18 being located on the side of the feed boardl which is opposite to that uponwhich the crank 17 is located.y By means of either Crank 17 or 18 the sprocket pinion 10, rigid with respect thereto, may be turned to cause the travel of the endless sprocket chain and the simultaneous and synchronousY rotation of the rollers v5 and the forward roller 7. v

The crank 17 is particularly serviceable for operation by the attendant when he is at the left of the board and ris loading a lift thereupon.

To prevent any of the rollers 5 andthe forward roller 7 from being turned by the l' shaking of the machine or the action' of lthe lift thereupon and thereby cause undesirable movement of the paper upon the same; I employ a suitable braking device, one form of braking device being illustrated in Figs.

1 and l-Y where I vhave shown a lbrakingclamp'19 embracing the shaft 11 of the next y tothe foremost roller 5 and comprising two jaws hinged together at one end of the clamp 'and coupled at the other end of theY clamp by an adjusting wing screw 20. The

. lbraking clamp is so adjusted that the shafts 11 may be turned notwithstandingthe brakving actionof the clampA but which braking 1 action is fsufficient vto preventthe rollers 1 from turning due to thef shaking of the machine and the action ofthe lift of .paper upon the rollers 5 andthe foremost roller 7. i

Inthe use of my device'v all of the sheets in lthe lift beeasilyadjusted tothe .position of feeding, this being true even of the Y last remaining bottom sheet, and I do not Y therefore wish to limit myself to the adjustment of thel entire lift of paper 'by means vof my invention.
